We got in touch with Rob Denton late last year to find out how the desulfator he purchased from us in October 2010 was faring after 5 long years. And we were pleased to know that it was still working fine.

Rob is a licensed amateur radio enthusiast based in Nottinghamshire and uses a 3 kilowatt uninterruptible power supply (UPS) with 8 batteries as backup power for his weather station computer and radio equipment. This was the testimonial he left us in 2010:

"I'm very pleased with the Infinitum Desulfator. So far it has renewed a full set of UPS batteries worth a total of £130 and a £80 110 amp deep cycle battery. That's a £210 in savings and it's now desulfating another deep cycle battery. Even taking into account the cost of the desulfator, I've saved £180 and it's still ongoing!"

We also found out then that Rob is a regular contributor to the quarterly journal GEO (Group for Earth Observation) and wrote an article which appeared in the GEO Quarterly No 33 in 2012. He was kind enough to search through his library to send us the image of the article. We have transcribed the article below for easy reading.

Improve The Performance Of Your ​Storage Batteries With A Desulfator

At home I make use of a number of rechargeable 12-volt lead-acid storage batteries (accumulators), rather like those used in motor cars. My weather station PCs, for instance, are backed up by a 3 kilowatt uninterruptible power supply (UPS) which uses eight 12V, 7.5 Ah sealed 'mat' batteries. At around £130 a set these don't come cheap, and mine were clearly reaching the end of their life as their backup time was down to 10 minutes after the power went off. I would normally expect much more than that.

It wasn't that my batteries had packed up; it was simply the fact that the lead plated inside them had become covered in non-conducting lead sulphate, theus rendering them unable to perform correctly. Most people replace their batteries at this stage but you know what? They simply needed desulfating.

I use the Infinitum desulfator, which seems a nice choice at a good price. As times get harder we tighten our purses more—so why did I suddenly splash out on a £30 battery desulfator? I'll tell you why: this little box of tricks has already saved me over £180.

​The desulfator works just great on car and truck batteries. You can simply leave it permanently connected on our car to keep the battery in tip-top condition. One thing that I must mention is that the desulfator is not a battery charger; it merely reconditions your batteries. It will not work with damaged cells. It requires a constant power supply to work and I use a small motorcycle battery charger in conjunction with my desulfator.

I am very pleased with my desulfator and can confirm it has saved me a lot money for a small outlay.
